Why Our Sleep Experts Loved It

becky says

The Sealy Holst Elevate Posturepedic mattress is one of the newer mattresses in the Sealy range and has a lot of features that you don’t see in other mattresses. You can thank the deep and luxurious plush top for that, which makes this mattress very comfortable to sleep on. This mattress also has high performance AlignSupport springs in the base layer that help to improve your quality of sleep with full body contouring and good zonal support that adapts to your movements based on how you sleep. If you are a side sleeper, then this is the mattress for you with the medium tension being ideal for your hip and shoulders to sink into. But if you are more of a back or stomach sleeper, this medium tension still offers enough support for your back and neck while you sleep.

This mattress is made with multiple different layers and moves away from the traditional base layer and comfort layer, instead including multiple comfort layers for further comfort. The result is a high quality mattress that helps to distribute your weight across the mattress, making it very comfortable. The mattress has a very soft top layer in the form of a unique plush top that we don’t find coming up very often in the UK, but rising in prominence in the US at a faster rate. Plush tops look and feel great and have many of the benefits of the pillow top but with extra rigidity and support.

The plush top adds to an already deep comfort layer in the form of Sealy Foam ComfortCare, a unique variant of foam that when combined makes it great for side, stomach and back sleepers who like to have a softer top layer. The mattress is made with a blend of foam and premium materials that are unique to Sealy, so it has just the right amount of bounce to make it comfortable. The mattress has a great build quality with an impressive 7-year guarantee against defects, and it is made in the United Kingdom. The mattress has a cooling SmarTex fabric in the breathable cover, making it a great option for people who tend to sleep warm.

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews.

Key Performance Indicators KPI question mark

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews. For example, a firm pocket spring support layer is more breathable and offers better back support but may prove unsuitable for side sleepers, the reverse is true for a soft-medium tension reflex foam support layer. This is one of 100+ datapoints considered when generating the below ratings.


*Assuming average weight, suitability will vary dependant on body type, use the quiz above for a more tailored guide.
  • Back Sleepers
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.


  • Stability
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.


  • Initial Odour
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

What Makes The Sealy Posturepedic Elevate Holst Mattress Great?

Features Sealy's own AlignSupport coil springs

AlignSupport Coil Springs are unique to Sealy and their new range of mattresses. This spring type is optimised to provide additional support in the lower back while also providing a measured all-round support that should suit many combination sleepers.

Senses your weight and responds accordingly

Soothing spinal alignment

When it comes to soothing spinal alignment, pocket springs in the support layer are the best way to achieve this. In fact, they are often recommended by healthcare professionals as a way to improve posture and alleviate back pain. Pocket springs are able to provide this level of support because each spring is individually encased in its own fabric pocket which allows the springs to move independently of one another, providing targeted support to specific areas of the body.

Twice tempered for enhanced durability and stability

UniCased edge support system

Reduces 'roll-off' feeling and increases sleeping surface

Blend of plush foam layers provide cosy comfort

Medium firmness - the ideal feel

Stylish quilted cover

A quilted mattress cover provides an extra, albeit limited layer of padding and comfort to your mattress. It also helps to protect your mattress from wear and tear, and can extend its lifespan. Quilted covers have a good degree of breathability which can help promoted airflow when paired with other materials, resulting in a cooler nights sleep.

Treated with ProShield and SmarTex treatments


This product is unlikely to cause any sort of allergic reaction. Ideal if you suffer from any sort of allergy problems

Pressure-relieving properties

A mattress with pressure-relieving properties can help to reduce pain and improve comfort for people who suffer from conditions like arthritis, fibromyalgia, and other chronic pain conditions. When choosing a mattress, it is important to consider the firmness, support, and pressure-relieving properties that will best suit your needs.


Single sided means only one side is comfy. Positives are you only need to rotate the mattress occassionaly rather than the more cumbersome rotate and flip. Downside is the lifespan of the product may suffer as a result, only marginal, but worth mentioning.

100% recyclable at the end of its life

All core components within the mattress have been manufactured utilising specific materials that allow for easy recycling of the entire product. 

Developed with the Orthopaedic Advisory Board

The Mattress was developed in collaboration with the Orthopaedic Advisory Board to provide optimal support and comfort for people with back pain. The board consists of leading specialists and experts who have extensive experience in the field. The mattress is designed to provide proper support for the spine and joints, and to reduce pressure points that can cause pain.

Depth: 30cm

With a depth of 30cm, this mattress is quite thick and featuring a fair amount of heft. While quality is not necessarily determined by depth, it does go some way toward allowing good quality fillings.

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

7 Year Guarantee

With a 7 year warranty, you are getting extended protection against the unthinkable. Should anything go wrong within the given period you will be covered. This is important because a mattress is a considered purchase and one that needs to be protected.
